A change that sails aimlessly around like a ship without a helm and compass will not reach any port. It should be clearly defined in which direction the change goes. "It is the job of the social sciences to provide guidance in this time of change and uncertainty." This responsible task should be performed by scientists. The possibilities that the 20th century offered mankind have been improved by technical development to such an extent that human reason cannot understand it. The uncontrollable and incomprehensible speed of this development will continue to astonish us and, as a consequence, create a kind of uncertainty. This book has been translated with Artificial Intelligence.
